MIm20c Posted April 28, 2017 Report Share Posted April 28, 2017 Wondering how I should approach a single cylinder running cold in cruise. Can the baffling be adjusted slightly or should I not worry about it. It gets really cold in MI over the winter and would like to keep more heat in the cylinder.

smwash02 Posted April 29, 2017 Report Share Posted April 29, 2017 100 degrees is a pretty big delta given the EGTs being pretty in line. I would suspect the probe. Swap two and see if it follows the probe or the cylinder. 1 Quote Link to comment Share on other sites More sharing options...
M20F Posted April 29, 2017 Report Share Posted April 29, 2017 What is your EGT peaking at 1481? Quote Link to comment Share on other sites More sharing options...

It all depends on where the probe is placed in the exhaust; move it a half inch, the value will change. That's why everyone says the absolute values don't matter, just distance from peak. 2 Quote Link to comment Share on other sites More sharing options...
AlexLev Posted April 29, 2017 Report Share Posted April 29, 2017 My #1 cylinder can get down to 246 in the winter time. Trust me, it's a good thing as when the temperatures get up to 85F, it will go up to 320, etc. Enjoy the extra cooling, I was concerned about it, but decided it wasn't a problem and actually a good thing after speaking to a few people. 1 Quote Link to comment Share on other sites More sharing options...
par Posted April 29, 2017 Report Share Posted April 29, 2017 On cold days, I've seen similar results. I don't think I'd lose any sleep over it. 1 Quote Link to comment Share on other sites More sharing options...

I understand my question was is that where his is peaking at, nothing more. 1 Quote Link to comment Share on other sites More sharing options...

Just received the plane so I don't have the data to answer your question. The egt's look well balanced for a carb engine. I was just wondering if anything could be changed to help in cruise. These temps were on a nice 60 degree day. I'm not sure what the readings will be when the temps drop 60 degrees. Quote Link to comment Share on other sites More sharing options...

tony Posted April 30, 2017 Report Share Posted April 30, 2017 My number one CHT runs cool too. The EGT is fine. Its not the probe because I swapped it with another one. I don't worry about it. 1 Quote Link to comment Share on other sites More sharing options...

Configured correctly you can delete that field and add FIVE MORE fields of your choosing below your existing ones. One of my favorites is MPG! 1 Quote Link to comment Share on other sites More sharing options...
carusoam Posted May 1, 2017 Report Share Posted May 1, 2017 Mlm, You really want to include the fact that you have a Turbo to get proper responses to your question. It is a good piece of info to have placed in your avatar area. Best regards, -a- Quote Link to comment Share on other sites More sharing options...
